Protocols, Communications, & Compromises

During a plant upgrade, an architect must connect legacy IEDs to a new TCP/IP instrumentation LAN. The IEDs have only RS-232 communication interfaces available. What should best be used to connect the IEDs?

  • A Data diode
  • B Engineering workstation
  • C Communications Gateway
  • D Industrial switch
Explanation

A communications gateway provides the required connection between RS-232 serial IED interfaces and a TCP/IP Ethernet instrumentation LAN, typically performing serial-to-Ethernet and protocol conversion.
